To investigate the anti-impact behavior and loading rate sensitivity of bamboo fiber reinforced composite (BFRC) beams, low-velocity-impact flexural experiments were performed under impact velocity changing from 2 m/s to 10 m/s. Quasi-static flexural tests were carried out under the same conditions to supply a quasi-static reference to the dynamic performance. Velocity-dependent effects of the impact force, the velocity, the impulse, the displacement and the absorbed energy were revealed by the weight-dropping experiments. The impact force, the energy absorption and the impact toughness increase nearly linearly to the impact velocity. These rate sensitivities of the BFRC beam were expressed quantitively by linear fitting equations, providing a basis to design shock and explosion resistant BFRC structures.

为了研究竹纤维增强复合材料（BFRC）梁的抗冲击性能和加载速率敏感性，在冲击速度从2 m / s更改为10 m / s的情况下进行了低速冲击弯曲试验。在相同条件下进行了准静态弯曲试验，为动态性能提供了准静态参考。通过减重实验揭示了冲击力，速度，脉冲，位移和吸收能量的速度依赖性效应。冲击力，能量吸收和冲击韧性几乎与冲击速度成线性关系。BFRC梁的这些速率灵敏度通过线性拟合方程式定量表示，为设计抗冲击和防爆的BFRC结构提供了基础。
